Answer
Coloman's father was Géza I, the Grand Prince of the Hungarians from 997 to 1001 and again from 1003 until his death in 1038. He played a crucial role in the Christianization of Hungary, initiating significant religious and political reforms. Géza I established a more centralized government and strengthened Hungary's international relations, laying the foundation for his son, Coloman's, successful reign as King of Hungary from 1095 to 1116.
